mesne assignments, to Knapp-Monarch Company, St. Louis, Mo., a. corporation of Delaware Application May'lll, 1946, Serial No. 668,952 11 Claims. (Cl. 251-134) My present invention relates to an aerating bottle or the like in which liquid, such as cream or the like, is adapted to be aerated or similarly treated, although the invention may be applied to other uses such as in connection with syphon bottles.

One object of my invention is to provide an aeratol having a control valve structure of simple, durable, and inexpensive construction.

Another object is to provide a control valve structure in the form of an assembly which may be readily removed from the aerating or syphon bottle to permit cleaning, the parts being held together in a novel manner, and all those parts requiring cleaning being exposed for doing a quick and thorough job of cleaning in a minimum of time.

Still another object is to provide a Valve assembly which when removed from the bottle leaves comparatively short and direct passageways in the bottle head that can be eiectively cleaned in a minimum of time.

A further object is to provide a valve structure which may be readily operated by depressing a hand lever after the aerator has been lled with liquid and the liquid aerated, the operating lever being removable with the valve structure when the valve structure is removed for cleaning.

A still further object is to provide a valve assembly in which the valve parts remain assembled instead of being capable of coming readily apart as in my copending application, Serial No. 562.554, led November 8. 1944. now Patent No. 2,484,232. issued October 11, 194.9.

j With these and other objects in view, my'invention consists in the construction, arrangement and combination of the various'parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of an aerator or the like embodying my invention.

Fig. 2 is an enlarged vertical sectional view through the aerator showing the valve in closed position. a

Fig. 3 is a further enlarged view showing the valve in opened position and by dotted linesl in closed position. e

Fig. 4 is a sectional view on the line 4-4 of Fig. 2.

Fig. 5 is asectional View similar to Fig. 3 showing the valve assembly removed'from the vase head for cleaning and showing how the parts stay together, and

Fig. 6 is a sectional View on the line 6-6 of Fig. 5 showing the retainer ring in retaining position.

On the accompanying drawings I have used thev reference numeral I0 to indicate a vase adapted to receive liquid, such as cream or an ice cream mix. Detachably mounted on the vase Il) is a vase head I2 provided with screw threads I4 adapted to coact with threads of the vase I0 in a well known manner. So that the head may be attached and detached relative to the vase as desired, the screw threaded connection includes a gasket to prevent leakage, but the gasket is not shown as it forms no part of my present invention.

In the vase head I2 I provide a vertical passagewayr I 6 andl a lateral passageway I8. The passageway I6 terminates in a valve seat 20 and the passageway I8 leads to a decorating nozzle 22 screwed into the vase head I2.

The vase head has a pair of bores 24 and 26 aligned with the passageway I6 and of different sizes with the transition from one size to the other forming a shoulder 28. A combined gasket and valve plug element A is provided having a valve plug portion 33, a cylindrical diaphragm portion 32, and a gasket ring portion 34. The

element A may be made of rubber or the like'and the gasket ring 34 thereof seats on the shoulder 28.

For seating the gasket ring 34 on the shoulder 26, I provide a sleeve 36 having an inturned flange 38 at its lower end and an out-turned flange 40 at its upper end. The flange 38 is adapted to contact the gasket ring 34 and a closure nut 42 is-adapted to contact the flange 40. The nut 42 is knob-like in character and is threaded onto the upper end 44 of the valve head I2, which upper lend is threaded for this purpose. The upper end 44 has a notch 46 therein with which a displaced portion 48 of the sleeve 36 coacts for preventing rotation of the sleeve 36 relative to the head I2.

A valve stem S is provided having a head 50 removably embedded in the valve plug portion 33" of the element A, and an enlargement 52 between its lower and upper ends. A spring 54 is mounted between the enlargement 52 and the closure nut 42 for normally seating the valve plug 36 on the valve seat 20.

The sleeve 36 is slotted at one side, as indicated at 56, and the head I2 has a slot 58 aligned pression 62 for pivotal coaction therewith. The

ring while inserting it through the threads of li the nut 42. The ring is then permitted .k,to..ex pand into an annular groove 'I2 cut into the nut to a depth approximately that of-,the lai-gesti diameter of the threads in thenuta Practical operation In the operation of my valve structure, ,the vase I having been lled with cream or the like and the cream aerated bythe introduction of gas underpressure, the yapparatus*can be used vfor dispensing the aerated cream by tipping it to an inverted position with the nozzle 22 pointing approximately downward.- The valve may then be opened -frorfrthe position of Fig.- 2 to thepositionof Figgp3 by depressing the handle Hi- The discharge of aerated cream can be controlled by thedegree of depression of the handle and by the length ottime it is depressed.

When it is desirable to clean the valve structure-,'this'may be readily done byunscrewing the knob- 42 fromthe upper end 44 of the valvehead scr-that the entire valve 'assemblyfas Ashown in Iig.-5, may-'bevremoved from ythe /aerator or syphon. An inspection of Fig. 3 makes it evident that the only surfaces needing cleaning` aside from the interior ofl the Yvase l0 and I2 are the passageways- I6 and I8, the nozzle 22, the bore'24, and-the portions 30 and 32 of the -element-A. These portions 3l'and 32 are fully exposed in Fig. 5. While the valveparts remain inassembled position and whileY the valve structure is removed, it--'isY a comparatively easy-V matter to clean `'the passageways I6 and i8 and the v-bore 24 with a small Lbrush, the nozzle 22- being removed during this operation'if desired. The nozzle can then be cleaned separately.

My disclosed arrangement makes-for convenience oicleaning the valvestructure without the parts fallingr apart or being otherwise dis-assem bled except when required. g In that case, vthe retainer ring e8 may be removed -so that the sleeve 36 can be removed from the nut 42 and -the element A can be removed from the head D off the stemS. Thereafter, the handle the stem- S,

and the spring 5 4 can be; removed and replaced, or other service performed on thev device.4 While the parts*` are in the position of- Fig-5; the spring 54 tendsto retain the handle H against the flange 38lofv the sleeve V6 and the parts thus are held against any-:looseness between them.

Some changes may be made in the construction and arrangement of the parts of mydevice without departing from'the real spirit'and purposeof myfinvention, and it is myintention Yto coverbylmy claims anymodiedforms of struc-A ture or use of mechanical equivalents which may be reascnablyincluded within their` scope .with out' sacricingyany ofr the advantages: t'hereoii.-`
